Physics Calculators: Force, Energy, Motion and More
Physics calculators for students and anyone checking a calculation. Each one uses the standard formula, shows the units and lists the constants it uses, such as the value of g.
Results update as you type, so you can see how changing one value affects the others.
Acceleration and SUVAT CalculatorSolve constant acceleration problems, including simple speed change over time, from any three of s, u, v, a and t.Projectile Motion CalculatorFind range, flight time and maximum height from launch speed, angle and height, including a simple drop.Wavelength and Frequency CalculatorConvert between wavelength and frequency for light, radio and sound, with photon energy.Specific Heat CalculatorFind the heat needed to change a temperature, or solve for mass, specific heat or temperature change.Half-Life CalculatorFind the amount remaining, time elapsed, half-life or starting amount for radioactive decay.Pendulum Period CalculatorFind the period and frequency of a pendulum from its length, with an allowance for wide swings.Force CalculatorSolve for force, momentum, impulse, circular motion, gravity between masses or charge attraction.Work, Energy and Power CalculatorSolve kinetic energy, potential energy, work and power, or efficiency, filling in whichever value is missing.Pressure and Density CalculatorSolve pressure, density, the pressure at depth in a fluid, or whether an object floats.Orbital and Escape Velocity CalculatorFind the orbital speed, orbit time and escape speed at a height above a planet, moon or star.Refraction and Snell's Law CalculatorFind the angle light bends when it passes between materials, and the critical angle.Speed, Distance and Time CalculatorSolve for speed, distance or time, work out running pace and predict a race finish time.
